(Portland, OR) -- Portland's population is growing, but its police force isn't growing along with it. The Portland Police Bureau says it has the same number of officers it had in the 1990s even though the number of residents has grown to more than 600-thousand. The bureau tells KATU-TV the situation is being made worse with many police officers retiring or choosing to leave for other agencies. Officials hope more recruits will be attracted to the police bureau under its new contract, which was approved by the Portland City Council last October.
